Cities worldwide watch London to see if Ulez can get up to speed
The Guardian says The controversial expansion of London’s ultra-low emission zone (Ulez) on Tuesday will be watched closely by policymakers around the UK and the world, as other cities weigh up whether to introduce similar schemes.
One key question is whether low-emission zones make financial sense for cities that introduce them. City administrations must weigh up the health benefits, any income from tolls and fines, the positive and negative effects on businesses and the cost to affected residents.
Since its initial rollout in 2019, the existing Ulez – which covers central London – has reduced nitrogen oxide and nitrogen dioxide emissions across the whole city by 23%, according to the London mayor’s office.
An analysis by the University of York found that Ulez, the congestion charge introduced in 2003 and the less strict low emission zone covering all of London, introduced in 2008, had reduced the probability of long-term health conditions by 22.5%, other health conditions by 29.8% and the amount of sick leave taken by 17.7%.
